SAFETY PIN.

Application filed February 16, 1920, Serial No. 359,144. Renewed July 6,1922. Serial No. 573,190.

To all whom it may concern:

Be it known thatI, STEPHEN OLoP, a citizen of the United States,resident of Denver, in the county of Denver and State of Colorado, havemade a certain new and useful Invention in Safety Pins; and I declarethe following to be a full, clear, and exact description of the same,such as will enable others skilled in the art to which it appertains tomake and use the invention, reference being had to the accompanyingdrawings, and to letters orfigures of reference marked thereon, whichform a part of this specification.

Figure 1 is a perspective view of the invention.

Figure 2 is a plan View of the same.

Figure 3 is a side view of the same.

Figure 4 is a detail cross section through the coil housing. I

Figure 5 is a similar view of the housing for the point of the pin.

Figure 6 is a perspective View of a modification of the inventionwherein the outline is elliptical.

Figure 7 is a detail section showinga coil housing of seamless form.

Figure 8 is a similar view of a seamless housing for the point of thepin. I

The invention has relation to safety pins and particularly to suchpins'having side bars constituting a frame, and a pin located centrallyof said side bars and pro- Vided with a resilient end coil serving tomove the pin outwardly away from said side bars when the former isreleased from its guard or housing, said coil located substantially atright angles to the plane of the side bars or in a plane angularlydisposed to and intersecting the plane of the side bars, the objectbeing to reduce the projection of the coil beyond the plane of thesidebars upon the face of the device occupied by the pin proper, wherebythe side bars or frame of the pin is adapted to lie close to the goodsor garment, being not held away from said goods or garment by -an endcoil the major portion of which lies uponthe inner side of said sidebars. Other objects and advantages will hereinafter appear.

In the accompanying drawings illustrating the'preferred embodiment ofthe invention, the numeral 2 designates parallel side other end into acoil 4 which may be disposed-in a plane nearly or. substantially atright angles to the plane of the side bars, but is preferably arrangedaslant or having its axis oblique to the plane of the sidebars, as shownin Figures 4 and 7, a pin 5 projecting from the upper terminalof saidcoil parallel to theside bars and located centrally therebetween. I

Preferably the end-coil 4 is so arranged that it projects above andbelow the sidebars and, a'sshowmthe sidebars being assumed to lie .in ahorizontal plane, the said end-coil 4 projects above and below saidplane to an equalextent, substantially;

A housing 6 for the coil 4 has a dished bottom 7, and a reversely dishedtop 8, which also respectively project downwardly "and side bars to anequal extent.

A housing 9 for the point of the pinlikewise has adished bottom 10 and areversely dished top or guard 11 respectively projecting below and abovethe plane of the side bars to a similar or. equal extent. The side ofthe safety pin bearing the pin proper is the inner side, which liesadjacent to the garment or goods, and it will be obvious that by sinkingthe. end coil between the side bars so that it will project equallythereof at the-inner or garment side and atthe outer side, the frame ofthe pin orthe pin as a whole will be brought asclose to the garment orgoodsas is consistent with a well balanced pin, which will prevent anyappreciable pivotal movement or rocking of the pin frame upon the pin.proper as-a center when the latter is engaged with the goods. Thehousing for the end coil lies close thereto and these advantages areretained, said housing being made with lateral members 12 bent inwardlyat .13, around theside bars and extending inwardly thereof, and with anend member 14 reversely bent or bent upon itself to form-thetop orguard, the'latter having lateral extensions 15 located between thedished bottom 7, and the inward projections 13, being clamped in suchposition when the metal is stamped or die struck.

The housing for the point of the pin projectingas stated equally aboveand below or at each side of theplane of the side bars is provided withlateral members 16- bentinwardly over the side bars at 17 andextendingthence parallel to'the dished bottom close thereto at 17 and havingterminal bends 18 extending outwardly or between the side bars centrallythereof to form a ridge 19, which terminates at a point just beyond ornearly in line with the side bars. This housing has an end member 20which is bent reversely to form the guard or top, reversely dished overthe aforesaid ridge, the point of the ridge being substantiallyconcentric of the concavity of the said top and spaced apart therefromand also spaced from the extensions 17 to admit the point of the pin,the sides of said dished top being spaced apart at 21 from the inwardbends 17 to form passages 22 for entrance "and eXit of the pin point.

These housings may also be made seamless, as illustrated in F igures 7and'S, by means well known in the art.

The pin is connected to the coil by a bend, in order to provide aworking clearance between thepin and edge of the housing;

This bend permits the forward edge of the housing to be brought downnearer to the planeof the side-bars, thereby reducing the tendency ofbeing caught by or engaging with materials brought into contact with thesafety-pin in use. 7

The slanting position of the coil imparts to the piercing-pin 5,inaddition tothe main resiliency in an upward direction away from theplane of the side-bars, a sufiicient lateral resiliency to enterthe-housing for the pin- 7 point automatically when placed opposite oneof the side-passages 22, thereby enabling the safety-pin to be morereadily manipulated by one hand. It, moreover, permits the housing to bemade flatter and hence to project less above the material to which thepin is attached. I

As best shown in Fig. 3, the said bend is first downward below the edgeof the housing 6 and then upward; This downward and then upward bendpermits the pin to be properly spaced with relation to the sidebars toallow the fabric intercepted by the said side-bars to lie flat and atthe same time to afford said working-clearance and to permit the edgeofthe housing to be brought down low enough to avoid a tendency toengage with or to be caught in articles brought in contact with'the'pin-attachment.

I claim:

1. In a safety-pin, a frame comprising two side-bars jand a resilient 1pin arranged between said Tside-bars and hinged to the frameby'a coil,in combination'with a housing 'at 'one end of the'frame and comprising acatch for thepin-point, the bottom'of said housing being dished awayfrom the frame.

2. In a safety-pin,"a frame comprising two side-bars and a resilient pinarranged betweensa id side-bars and 'hinged'to the frameibyi a coil andextending above and below the frame, in combination with ahousing at oneend of the frame and comprising a catch for the pin-point, the bot tomof the housing extending below the plane of the frame, and a housing atthe other end for the coil, the bottom of said housing also extendingbelow the plane of saidframe.

8. In a safety-pin, a frame comprising side-bars and a pin arrangedbetween said side-bars, in combination with a spring con necting the pinto the side-bars, said spring being arranged obliquely with respect tothe side-bars, and a housing for thepin.

I. In a safety-pin, a frame comprising side-bars and a pin arrangedbetweensaid side bars, in combination with an end-coil connecting thepin to the side-bars, said coil being arranged obliquely with respect tothe plane of the side-bars, and a housing-for the pin. v

5. In a. safety-pin, a frame comprising side-bars, an end-coil extendingbelow'the plane of said side-bars, and a pin extending from said coiland arranged between said side-bars, in combination with a housing forthe coil projecting below said plane, and a housing for the pin-pointalso extending below said plane.
